Clone Number:

ICRF44

This antibody has been used to optimise flow cytometry-based immunophenotyping of whole-blood samples. The results have not yet been published. Multi-colour antibody panels were designed to identify a number of lymphocyte populations and tested to ensure appropriate compensation was possible. CD11b was used in a ten-colour panel to help distinguish myeloid derived suppressor cells (MDSCs). It is easy to use and gives clear staining.

Results Summary

Clear staining that, in combination with HLA-DR, helped identify myeloid derived suppressor cells (MDSCs). Titration optimisations showed we could reduce the volume of antibody used with no detriment to the results. Prior to analysing samples, erythrocytes were lysed using 1.5 mL 1xPharmLyse (BD, cat#555899) at room temperature for 30 minutes. This antibody fit well into a ten-colour panel with no compensation issues.

Summary

The Good

Clear staining of CD11b+ cells that is useful for FACS analysis.

The Bad

The antibody has only been tested for flow cytometry.

The Bottom Line

An easy-to-use antibody that provided good clear staining.
